This is technically a more complex problem then you think. There was an John initiative to evolve an isObjectLiteral(obj) http://gist.github.com/153271 I made an solution for it at http://gist.github.com/158651 that passes all tests, but that shows how it complex it is too. I think it would be an overhead.

It is weak, but in case of $.each you normally know exactly witch proprieties has an object. -- You received this message because you are subscribed to the Google Groups "jQuery Development" group.
